Application filed August 3, 1897. Serial No. 646,997, (No model.)

To all 107mm fr may concern.: held in position by the *cap as required to Be it known that I, EDWARD SCHAEFER, of form a tight joint between the cap and the 55 the city of St. Louis, State of Missouri, have tank. Anannularint'eriorly-screw-threaded invented certain new and useful Improvefiange 12 projects downwardly from the cap 5 ments in Fire-Extinguishers, otwhich the fol- 10 in position concentric to the ring 8.

Fig. 2 is an enlarged detail of said side pieces, the ring 2O connecting` vertical central section of the cap, the botthe lower ends of said side pieces, and the tlc-closing mechanism, and the bottle-suphorizontally-sliding door 21 closing the lower 7c porting rack. Fig. Sisadetail section taken end of the rack and holding the bottle in approximately on the line 3 3 of Fig. 2 and position. An ear22 projects horizontally outa looking in the direction indicated by the arwardly from the lower end of the side piece row. Fig. 4 is a horizontal section taken ap- 18. An ear 23 projects from the door 21, and proximatelyon the line-l of Fig. 2 and looka rivet or screw 24 is inserted through the 75 ing downwardly. Fig. 5 is a view in perear 22 and through the ear 23, thus forming spective of the conical packing-ring through a horizontal sliding connection between the 5 which the sliding bolt operates and which is door 21 and the side piece 18. The door 21 located on top ot the cap. Fig. Gis a View in is a disk large enough to close the opening perspective ofahard-rubberbushing through through the ring 20. A notch 25 is formed 8o which the sliding bolt operates and which is horizontally in the lower end of the side piece located in the center of the cap. Fig. '7 is a 17, and a projection 26 at the opposite side-of n detail view in elevation of the lower end of the door 21 from the ear 23 engages in said the bottle-supportingrack as seen looking in notch 25. The screws 27 and 28 are inserted the direction indicated by the arrow 7 in through bearings in thelower ends of the arms 85 y Fig. 2. 14 and 15 and screW-seatedin the side pieces y The object of my invention is to provide a 17 and 1S, respectively, as required to form portable tire-extinguisher which may be dispivotal supports for the bottle-supporting l charged without inverting the tank and withrack. The door 21 swings horizontally unt-il out breaking the bottle. the opening through the ring 2O is unob- 9o Referring by numerals to the drawings, 5 structed. Then the acid-bottle 29 is inserted is the tank, which may be of anysuitable conupwardly through the ring 2O until the instruction. wardly-turned upper ends of the side pieces G is the discharge-pipe, which leads from 17 and 18 engage the upper ends of the botthe interior and near the bottom of the tank tle. Then the door21 is closed, thus holding 95 upwardly and outwardly through the top of the bottle securely in position in the bottlethe tank at one side of the cap, the hose 7besupporting rack. The screw-threaded, coning attached to the outer end of said pipe. nection between the fiauge 12 and the ring The tank 5 has an opening in the center of 13 forms a means of adjusting the bottleits top, through which the exteriorly-screwsupporting rack upwardly or downwardly to roo threaded ring 8 is'inserted, and the flange 9 suit the varying lengths of bottles. Ascrewprojects outwardly from the lower end of the threaded opening is formed through the cenring and engages the inner face of the tank. ter of the cap l0, and a hard-rubber bushing The interiorly-screw-threaded cap 10 is screw- 30 is screw-seated in said opening. The upseated upon the ring 8, and a packing-ring 11 per end of the bushing 30 is reduced in size, 105 engages the upper edge of the ring 8 and is thus producing the collar 31, which collar eX- tends upwardly above the upper face of the cap l0.

The conical packing-ring 32 has the lower end of its opening enlarged to receive the collar 3l, and said packing-ring is placed in position with its lower end resting upon the upper face of the cap l0 and upon the upper face of the bushing 30. The conical coilspring 33 is placed in position around the packing-ring 32, and the sliding bolt 34 is inserted downwardly through the bushing 30 and through the packing-ring 32. The packing-ring 35 is placed around the'lower end ofY the bolt 34, and the cap-shaped head 36 is screw-seated upon the lower end of said bolt and below said packing-ring. The stopper 37 is attached to the head 3G and engages in the mouth of the bottle 29. A head 38 is formed upon the upper end of the sliding bolt 34 and engages the upper end of the conical coil-spring 33 and holds said spring in position, the lower end of said spring resting upon the upper face ot the cap IO. Handles 39 project from the head for operating the bolt.

The arms 40 and 4l 'extend downwardly from the cap l0 upon opposite sides of the sliding bolt 34, said arms having the concentric cam-faces 42 and 43, respectively, extending from the lower face of the cap l0 on an incline to the lower ends of said arms and nearly across the lower ends of said arms, as shown in Fig. 3. The lugs 44 and 45 project outwardly from opposite sides of the cap 36 and engage the cams 42 and 43, as required to raise and lower the stopper 37. By rotating the sliding bolt 34 when the stopper 37 is in its depressed position, as shown in Figs. 2 and 3, the acid-bottle is securely closed and the conical coil -spring 33 engages tightly around the packing-ring 32, as required to compress the packing-ring and form a watertight joint between the sliding` bolt 34 and the cap l0, thus preventing the machine from leaking.

When itis desired to discharge the machine, the handles 39 are manually engaged to partially rotate the sliding bolt 34 and allow the expansion of the spring 33 to elevate said bolt, thus drawing the stopper 37 away from the mouth of the bottle and allowing the bottle to tip downwardly, as shown in Fig. l, thus discharging the contents of the acid-bottle into the liquid within the tank and discharging the extinguisher without inverting the tank.

lVhen the sliding bolt 34 is in its elevated position, as in Fig. l, the tension of the spring 33 pulls the packing-ring 35 firmly against the bushing 30 and the lower face of the cap l0, thus forming a water-tight joint around the sliding bolt 34. The hard-rubber bushing 30 around the slidingbolt 34 prevents said bolt from contacting with the metal composing the cap 10 and keeps the bolt smooth.

The handles 46 project upwardly and outwardly from opposite sides of the cap 10 for operating the same.

I claiml. In a tire-extinguisher, a sliding bolt op- 1 the wall, a conical spring around said packj ing-ring, and a stopper upon the inner end ot said sliding bolt, substantially as specified.

2. In a tire-extinguisher, the combination with a cap having an acid-bottle pivotally swung from its under side, of a rod arranged l for vertical movement through the center of the cap, a hard-rubber bushing screw-seated in said cap and around said sliding rod, a conical packing-ring upon said bushing and around said rod, a conical coil-spring around I said packing and around the rod, a iiexible ring passing around said rod beneath the bushing, acap carried by the lower end of said rod, and a flexible conoidal stopper carried by said cap, substantially as specified. g

3. In a lire-extinguisher, the combination with a suitable tank and a cap removably seated in position to close said tank, of a g frame vertically adjustable and removably connected to the under side of said cap, a q bottle-su pporting rack pivotally connected to the lower end of said frame, a rod arranged for vertical movement through the center of the cap, a hard-rubber bushing screw-seated in said cap around said sliding rod, a conical packing-ring upon said bushing and around said rod, a conical coil-spring around said packing and around said rod, and a flexible stopper carried by the lower end of said rod, substantially as specified.

4. In a lire-extinguisher, the combination with a suitable tank and a cap removably seated in position to close said tank, of a frame vertically adjustable and removably connected to the under side of said cap, a bottle-supporting rack pivotally connected to the lower end of said frame, a rod ar-V ranged for vertical movement through the center of the cap, a hard-rubber bushing screw-seated in said cap around said sliding rod, a conical packing-ring upon said bushing and around said rod, a conical coil-spring around said packing and around said rod, a exible stopper carried by the lower end of said rod, and means carried by the under side of the cap for locking the rod at its lowermost limit of movement when the stopper is in the mouth of the bottle, substan tially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
